It is important to know at any age!

One way to align yourself with the universal forces is to work with the metaphysical qualities of gemstones and crystals for health, energy, and balance. I invite you to enter into the sparkling, mystical world of gemstones, connecting us with the whole of creation, from microcosm to macrocosm.

and here is another

Titan: Titan, the tormented, hydrocarbon-slashed largest moon of Saturn--and the second largest moon in our Solar System, after Ganymede--could possess a subsurface, salty ocean that may well be as salty as the Dead Sea on Earth. The salty water could begin approximately 31 to 62 miles beneath Titan's icy shell, according to recent estimates. Meanwhile, on Titan's smog enshrouded surface, "life as we do not know it" could swim in alien lakes and rivers that flow with liquid methane and ethane hydrocarbons--instead of water.

and finally

The moon's orbit. The moon's orbit is not on the same plane as the earth's orbit around the sun. If it were, every time we had a new moon we would have a solar eclipse, and every time we had a full moon we would have a lunar eclipse. Instead, the moon travels in a track that goes well above and well below the earth. Still, on occasion it will travel in between the sun and the earth and in this case, there will be an eclipse.

Earlier theories suggested that the craggy outline of a region of the lunar surface, named Oceanus Procellarum--or the Ocean of Storms--had resulted from a large asteroid impact. If this theory had been correct, the basin it had dug out would represent the largest asteroid impact basin scarring the lunar surface. However, mission scientists, scrutinizing GRAIL data, now believe that they have discovered new evidence that the craggy outline of this rectangular region--approximately 1,600 miles across--was actually caused by the formation of ancient rift valleys.

"The whole process of generating porous space within planetary crusts is critically important in understanding how water gets into the subsurface. On Earth, we believe that life may have evolved somewhat in the subsurface, and this is a primary mechanism to create subsurface pockets and void spaces, and really drives a lot of the rates at which these processes happen. The Moon is a really ideal place to study this," Dr. Soderblom explained in the MIT Press Release.

However, when people ask whether mankind has the capability to go to the Moon again, unfortunately the answer is an absolute no. Even though mankind has much more advanced space technology as compared to 1960's; the current technology is not geared toward moon flight. In fact, even the US has lost the capability of the Saturn rockets due to the fact that production facilities have been dismantled. In time, even the know-how has become obsolete, as people who have worked in the Saturn program have retired or died. Hence, even if the US wanted to go to the moon today, a manned flight would be impossible for at least another decade.
